Abstract (en)
[origin: WO9101474A1] A hot isotropic press of the present invention is used to press an object (14) by applying thereto an isotropic high pressure at a high temperature in an oxidizing atmosphere in a high-pressure vessel (1) equipped with a heating unit (4) made of an oxidation-resistant material and provided with a heating element (6) having a high electric resistance at a low-temperature portion. The heating unit (4) made of an oxidation-resistant material has a heat-insulating layer (5) of an inverted cup-like shape wherein the heating element (6) is housed at the upper part thereof. A preheating element (7) is housed below the heating element (6) inside the heat-insulating layer (5). Further, a second heat-insulating layer (105) is disposed beteween the heating element (6) and the first heat-insulating layer (5) to enclose the element (6) and the preheating element (7) is housed below the heating element (6) in the lower part of the first heat-insulating layer (5).
